A very useful Web-based tool called the Global Powder Metallurgy Database now exists to search properties for nearly 2,500 powder metals. The database has been created by parts manufacturers and powder producers across the world through three trade associations: the Metal Powder Industries Federation (MPIF), the European Powder Metallurgy Association (EPMA), and the Japan Powder Metallurgy Association (JPMA). You an find detailed mechanical, physical and fatigue properties for materials identified by ISO or MPIF code. Materials include structural steels, stainless steels, soft magnetic alloys, bearings, and nonferrous. Once you discover grades with acceptable properties, the Web site guides you to specific contacts at suppliers. Data can be downloaded as Excel or FEA software files. Data for metal injection molding was added last year. Use of the database is free, but registration is required.
This grab-bag of new fasteners and adhesives work with a range of materials they can attach to, as well as a wide variety of applications. Several are for use in consumer applications, such as wearables or other compact electronic assemblies, and some of the adhesives have extended service temperature ranges and cure at room temperature.
Several of the new and noteworthy 3D printers in this slideshow are breaking some boundaries in build volume, new metals printing techniques, or working with high-profile development partners to ensure very high-quality parts and controls.
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
